In remote-sensing applications, incomplete data can result when only a subset of sensors(e.g., radar, infrared, acoustic) are deployed at certain regions. The limitations of singlesensor systems have spurred interest in employing multiple sensor modalities simultane-ously. For example, in land mine detection tasks, different sensor modalities are better-suited to capture different aspects of the underlying physics of the mines. Synthetic aper-ture radar sensors may be better at detecting surface mines, while infrared sensors maybe better at detecting buried mines. By employing multiple sensor modalities to address.
